I'd say it's 50/50.
there's certainly a big sigh of relief at cambridge when the 3 car set arrives!
the platform is usually pretty rammed

Depends where the capacity is needed... more likely some nifty timetabling, potentially have 2 units leave cambridge at similar times, could do a similar thing to Norwich in 90 service, a fast to Norwich stopping at Ely followed by the stopping service. Just a thought if it could be pathed

How occupied are paths north of Cambridge? There's GA Norwich and Ipswich, Cross country, great northern and Thameslink, plus freights.

But we will. They can't just be used because they are sitting there. The 3-cars still have no safety case approved either.

And if it weren't for the level crossings, would it be OK to have parts of both units off the platforms?

Indeed, hence the ‘if possible’ part of my post. Not just paths but platform occupation and conflicting moves at both ends too.

Sometimes we take two 170s for operational reasons & lock the rear unit out of use. This blocks level crossings but has no impact on the working of the train.

Why? There are several places on the network where that is the case.

Maybe because that's an AHB.

But if there where passengers in them they could not move through. I don't know anywhere where that happens.
I've boarded and alighted from a charter at Attleborough that blocked the crossing for several minutes.
The gates are down for so long anyway another minute or so would hardly have much impact.
It always slightly amuses me that a low speed road traffic and mostly low speed rail traffic location has the full monty barriers, obstacle detection etc interlocked to the signals. A few miles south there's an AHB on a 60mph road where all of the trains are at line speed. About 15 seconds between the yellow light coming on and the train hurtling through.
Yes I know the AHB had been there for years when standards were different and there's less traffic than through Attleborough.

I can't recall where, but I have come across exactly this somewhere recently. I think it might have been a 158+170 pair on the Highland Mainline.
First suggestion is in use on the DLR although that doesn't use signals. I guess signal placement would be the only limiting factor for that to be implemented?
I'm not sure about Brandon, but Attleborough doesn't have any signals at the end of the platforms. Thetford and Wymondham (and probably Attleborough for that matter) are long enough for 2 units. The minor stations that see 1 or 2 trains a day could be served by single unit sets.
But what the line really needs of course is a higher frequency of service. That would encourage more ridership than longer trains on the existing service pattern whilst reducing crowding and abiding platform length issues. That won't happen though unless/until Ely and Trowse are sorted out.

Have they managed to get any more than 3 units into passenger service now or is this going to be another very long drawn out changeover.
Is everyone waiting for Winter when there will be more slack in resources, hopefully!
Why is the 3 car taking so long to get it's safety case over the 4 car Class 755? Maybe they should have started with the 3!

How about not bothering with another unit between Ely and Cambridge and run a Ely to Kings Cross or Liverpool Street instead of terminating at Cambridge

Although Thetford has long platforms there is or was a problem there, long trains are banned in one platform
Think it's the down platform they are banned from,

Must be a new thing as the 12 coach charter I was on stopped there both ways, about 3 years ago. In any case slam door stock is surely different from new stock with DOO cameras?

Been told they keep failing, short set is still out and about

Yes but did they lock some doors on vehicles on the charter that were off the platform, which is what they do with the Jacobite Mk1s on the West Highland Line.
That's good news in one way anyway. If you like noisy 37s.
Ah right, sorry I misunderstood @CockneySparrow post and thought he was talking about some other issue caused by length.

They will need another 2 if the Wisbech line ever reopens

I think the charter has enough staff to cover all doors
Happens with 2 x 5-car IETs at (I think) Hayle on the Down platform.

I wrote it wrong, problem is platform ain't straight so guard or driver cant see all doors
The charter has enough support staff to solve the problem

Wouldn't be an issue on a FLIRT because it has DOO cameras so the driver can see each coach independently of any curve.

GTR already do that (with 8-car trains normally for the Ely terminators) - it's GA's stupidly cheap 'GA only' fares between Cambridge and Ely that are creating a rod for GA's own back...
